Review on Powerful and Precise: Unleash Your Potential with Sioux Force Tools Pencil Grinders by David Dortch

I used this tool a few hours a day at least 4 days a week for at least a few months until I sold it to a colleague when I had a Dynabrade turbine bought drove a grinder at 100,000 rpm which really sucked and had virtually no torque. So it did me no good and I totally regret that I bought this expensive post. I've used Sioux to rip through some very hard metal pieces with strong edges. So I put a lot of pressure on this tool. For the most part, it had good torque. The wedges in the pencil sharpener eventually broke after a few months but that was after a lot of brutal work had been done and these wedges are very easy to replace and cheap. This pencil sharpener also works well with titanium and inconel, which are very hard metals.
